GEARING MECHANISM FOR MOTOR-VEHICLES.

Specification of Letters Patent.

Patented Feb. 19, 1907.

Application filed March 3, 1906. Serial No. 304,001.

To all whom it may concern.-

Be it known that I, LESLIE Born FARMER, a citizen of the United States, residing at South Orange, in the county of Essex and State of New Jersey, have invented a Gearing Mechanism for Motor-Vehicles, of which the following is a full and complete specification.

This invention is an improvement in metor-vehicles of the class commonly known as automobiles, and relates more especially to the provision of improved gearing mechanism between the motor and driving-wheels.

The object-s of the invention are to provide a connection between a counter-shaft and the driving-axles of a motor-vehicle or automobile which shall be light in construction,

efl'ective in operation, strong and durable,.

and which shall transmit the power evenly and positively under the varying conditions in which such vehicles are used.

The invention consists in the peculiar construction and arrangement of the parts constituting the improved gearing in connection with the form of supporting-frame therefor, all as hereinafter particularly described, and specifically set forth in the appended claims.

In the accompanying drawings, Figure 1 is a plan view of my improved gearing mechanism for motor-vehicles or automobiles, showing so much of the supporting-frame or run ning-gear as is necessary to the application of the invention. Fig. 2 is a rear elevation. Fig. 3 is an enlar ed sectional view through one end of the ax e, showing the manner of connectin the driving shafts or axles. Fig. 4 is a detail illustrating a modification hereinafter referred to. Fig. 5 is a vertical sectional view through Fig. 4.

Like letters and numerals of reference indi cate like parts in all the figures of the drawin s.

n carrying out my invention the gearing mechanism hereinafter described is supported in a frame com rising a rear transverse bar or axle A, whic is provided near its op osite ends with downwardlyextending oops a, and at opposite sides of the latter the axle is cut away at its upper side (see Fig. 3) to receive the bearingboxes, in which are journalcd the cranked driving shafts or axles hereinafter referred to. The axle A is preferably made solid and of the required size to support the load it is intended to carry.

Between the loops of the axle A and u on the latter there are secured, by means of clips I), two reach-bars a and 0, which extend forwardly and merge in a loop portion a said reach-bars being braced intermediately by a cross-bar a". At the outer ends of the axle A are secured reach-bars a and a, which also extend forwardly and are connected to the loop portion of the aforesaid reach-bars by means of diagonal bars (1. Those roach-bars in conjunction with the connecting-bars and axle constitute the frame for supporting the gearing mechanism and being constructed in the manner shown forms a light and strong support.

Secured at the inner side of each loop portion 0. of the axle A are the upper and lower sections 0 and 0, respectively, of a bearingbox which supports one end of a cranked shaft or axle D, the latter being supported at the opposite side of said loop portion by means of a lower bearing-box section 0 in conjunction with the upper sections 0 c", and c, the intermediate section 0 forming a seat for one of the reach-bars a? or a, while the end sections 0 and c" are removable and contain Babbitt metal, as w, Fig. 3, the box (2 0 also being provided with Babbitt metal to provide the bearing-surf aces for the shafts D. These bearings are lubricated in any approved manner.

The lowerbearing-box sections 0 and c are secured to the axle A by means of screws 8, Fi 5, while the upper sections are all secure to said lower sections by means of bolts and nuts, as shown.

Each drivin shaft or axle D is provided with two cranlis d and d, disposed at right angles to each other, and the shaft is extended beyond the end of the axle, where it is formed into a spindle d to receive the wheel D, which is attached to said spindle, so as to rotate with the shaft. The shaft or axle D is provided with a collar d at the end of the axle and with a similar collar d at the inner end of said shaft, said collars holding the shaft against end thrust. The cranks of the shafts or axles I) turn in the loop portions a of the axle A, and in order to reinforce the latter at said loops removable loops E, correspending with the loops a, may be provided, (see Fi 4,) in which instance the ends of said loops 1i take the place of the bearing-box sections 0 and c", for which purpose said ends are flanged laterally, as at e, so thattheymay be bolted to the lower bearing-box sections. (See Fig. 5.)

Extending transversely of the supportingframe and parallel with the crank shafts or axles D D is a counter-shaft F, said countershal't being supported on the reach-bars a, a, a and a in boxes h, bolted thereon. The counter-shaft is provided With cranks f and j" on a line with the corresponding companion cranks d and d on the crank-shafts D and disposed with relation thereto that when connected by the rods 'i the operation of the counter-shaft will also turn the crank shafts or axles, said rods i being coupled to the cranks in the usual manner. The countershaft is also provided with a large bevel gearwheel M, which is in mesh with a beveled pinion N, the latter being on the rear end of a longitudinal shaft 12, driven by any suitable motor. (Not shown.) The large bevel gearwhcel M is provided with the usual differential gears which are inclosed in the casing m, fastened to the rear side of the large gearwheel M.

From the foregoing description, in connection with the accompanying drawings, it will be readily seen that I provide a gearing mechanism for motor-vehicles or automobiles which is simple in construction and will transmit the power in an effective manner, inasmuch as the double set of crank connections will evenly balance the driving-gear and insure an easy running of the vehicle under varying conditions of road, &c. The construction of bearings for the crank-shafts which carry the drive-wheels provide that said bearings may be easily and conveniently examined and repaired or renewed, if necessar l faving thus particularly described my invention, I do not wish to be limited in my protection to the construction shown and described, as obvious changes may be made in certain details without sacrificing any of the advantages of the invention, all within the spirit and scope of my claims.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a motor-vehicle or automobile, the combination with the frame comprising the axle A and reach-bars extending forwardly therefrom, said axle having loops near the ends thereof, of the driving shafts or axles D bridging the loops of the axle A and having double cranks disposed in said loops, one end of each driving-shaf t being extended beyond the end of the axle and formed into a spindle; together with a counter-shaft journaled on the reach-bars and having two pairs of cranks connected to the cranks of the driving-shafts by rods i, and means for turning the countershaft.

2. In a motor-vehicle or automobile, the combination with the frame comprising the axle A having the depending loops a near its ends, of bearing-boxes disposed at opposite sides of the loops, and crank-shafts u journaled in said bearing-boxes and extended at one end beyond the axle w here it is formed into a spindle to receive the wheel; together with counter shafts supported in boxes mounted. on the reach-bars and having crank portions, rods connecting the counter-shafts to the crank-shafts, a large bevel gear-n heel connected to the counter-shafts, and means for turning said bevel gear-w heel.

3. In a motor-vehicle or automobile, the combination with the frame comprising the axle A having the depending loops (1 near its ends, parallel reach-bars extending forw ardly from the axle and connected together at their forward ends; of bearing-boxes disposed at opposite sides of the loops, the bearing-box at the outer end of the axle comprismg a lower section and three upper sections, the intermediate upper section forming a seat for the outer reach-bars, crank-shafts supported in said bearing-boxes and extended beyond the end of the axle vs here they are formed into spindles to receive the driving wheels, and a removable loop portion the ends of nhich form a part of the bearing-boxes, said removable loop portion being opposed to the loop portion of the axle; together vith counter-shafts supported on the reach-bars and having cranks, rods connecting the counter-shafts to the driving-shafts, and a bevel gear-wheel for impartlng rotation to the counter-shafts, substantially as herein shown and described.

4. In a motor-vehicle or automobile, the combination, of independent crank-shafts carrying the drive-w heels, said. shafts having each a double crank disposed at right angles to each other together with counter-shafts having corresponding cranks, rods connecting the counter-shafts to the crank-shafts, and means for imparting motion to the countershafts, substantially as show n and described.

5. .In a motor-vehicle or automobile, the combination, of separate shafts carrying the drive-wheels, said shafts each having a plurality of cranks disposed'at an. angle to each other, a counter-shaft having corresponding cranks, rods connecting the cranks on the counter-shaft to the companion cranks on the wheel-shafts, and means for imparting motion to the counter-shaft, substantially as shown and described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
